Delta Air Lines CEO, Rick Bastian, has raised his Q1 revenue guidance to a high single digits and at least 50 to 90 cents per cent. This comes amid a surge in Jet Fuel, ongoing TSA shortages, and a potential increase in fuel prices. Bastian noted that Delta's consumer base remains healthy and that 90% of its revenue now comes from the top of the K-shaped economy. He also commented on the ongoing government shutdown, which has left TSA officers working without pay. Despite this, Bastian said that Delta’s brand remains strong and that weaker airlines have no choice but to pass on rising fuel costs.
